Definitions

  • the invention relates to a pressing-bending machine of flat glass sheets.
  • the geometry obtained for a curved or curved glass sheet can be defined by an appropriate adjustment, on the one hand, of the transverse elements and, on the other hand, longitudinal elements of the assembly peripheral of the shaping organ.
  • the rolls of support and conveying which extend from one edge to the other of the peripheral assembly effectively supports the sheets of glass and adjustable longitudinal elements are compatible with these rollers.
  • the elements can be changed, the elements longitudinal remaining in place on the machine and being set to take account of the new profile.
  • the invention also allows you to adjust the pressure exerted by the matrix forming bodies and punch on the edges longitudinal sheets of glass, which allows correct certain faults noted during manufacturing.
  • the invention allows rapid change of manufacturing, without modification of the rollers of the conveyor / support device, and great flexibility in production course.
  • this machine incorporates one or more of the features mentioned in the claims dependent annexed.
  • the machine 1 shown in Figures 1 to 5 is intended for shaping outgoing glass sheets 2 a heating furnace not shown. Heating at the interior of the oven can take place by radiation, conduction, convection and / or any other method appropriate.
  • the sheets 2 are moved by a conveyor 3 according to a direction of advance X-X '.
  • the conveyor 3 comprises rollers 31 capable of rotational movements around their central axes respective which are generally perpendicular to the direction X-X 'and generally horizontal, which their allows to support the sheets 2 whose surfaces 26 are supported on the upper generators of the rollers 31.
  • rollers 31 may be rotated by a motor 32.
  • Machine 1 has a lower press plate 4 and an upper press plate 5, these plates 4 and 5 being susceptible to a reconciliation movement or spacing in a direction Z-Z 'perpendicular to the direction X-X 'and, in practice, generally vertical.
  • the lower plate 4 comprises several beams 41 which support a female mold member or matrix 6.
  • the upper plate 5 comprises beams 51 which support a male organ or punch 7.
  • Means such as electric motors 42 and 52 associated with references to angles 43 and 53 and with means of linear guidance not shown are respectively provided to move the plates 4 and 5 and the members 6 and 7 parallel to the direction Z-Z '.
  • Organ 6 is more particularly visible on the Figure 3. It includes two belts 61 extending along directions generally parallel to a direction Y-Y ' itself perpendicular to the directions X-X 'and Z-Z'.
  • the belts 61 are each connected to a beam 41 by adjustable supports 62.
  • the belts 61 define the profile geometry of a glass sheet after bending and are adjustable in the direction Z-Z 'thanks to the supports 62.
  • the belts 61 are arranged respectively at proximity of the two transverse edges of the member 6, that is to say of its front and rear edges.
  • Some drive rollers 31 extend between the belts 61, from one edge to the other of the member 6. They therefore effectively support glass sheets 2 and do not are not moved vertically or transversely.
  • Rollers 63 are aligned along two longitudinal edges B 6 and B ' 6 of the member 6. More specifically, the rollers 63 are interposed between the rollers 31, the respective axes X 63 of the rollers 63 being aligned with the edges B 6 or B ' 6 which are generally rectilinear and parallel to the direction X-X'.
  • rollers 63 In FIG. 3, only a few rollers 63 have been shown for clarity of design. In practice, the number of rollers 63 depends on the desired length for the matrix-forming member 6.
  • Each roller 63 is mounted on a bracket 64 supported by a post 65, all the posts 65 with the same longitudinal edge B 6 or B ' 6 being themselves supported by a beam 66 capable of vertical and horizontal movements relative to the plate 4, these movements being represented by the double arrows F 1 and F 2 in FIG. 4 and being respectively parallel to the directions ZZ 'and Y-Y'.
  • Mechanical jacks 67 are provided to move the beam 66 and the elements that it carries, at each edge B 6 or B ' 6 of the member 6 relative to the plate 4. It is thus possible to adjust the position rollers 63 relative to the plate 4 independently of the adjustment of the position of the belts 61 relative to the latter.
  • the cylinders 67 can be driven by motors electric. Pneumatic, hydraulic or electric can be used instead of cylinders mechanical 67.
  • the adjustment of the position of the rollers is independent belts 61 and rollers 31, these rollers not being not moved during this adjustment.
  • each roller 31 is provided with a hollow zone 311 in its central part, this hollow zone making it possible to receive and guide a bent glass sheet, as shown in phantom in this Fig. More precisely, each roller 31 comprises a tube 312 of relatively small diameter inserted into two tubes 313 and 314 of larger diameter, the tubes 312 and 313, on the one hand, 312 and 314, on the other hand, being immobilized one compared to the others thanks to pins 315 and 316.
  • the area 311 is thus formed by the difference in the external diameters of the tubes 312, 313 and 314.
  • the generator of the roller 31, which is formed by the meeting of the generators of the tubes 313, 312 and 314, is thus concave at the level of the zone 311.
  • the pressing of the curved glass sheet on the roller 31 can take place at two points P 1 and P 2 or on a line, which allows guidance longitudinal of the curved glass sheet.
  • the glass sheet 2 can be guided at a single point situated at the bottom of the zone 311.
  • Each roller 31 is surrounded by a sheath 33 produced made of aramid fibers, silica or metallic micro-threads and flexible enough to deform at the zone 311 in the part on which the sheet 2 rests.
  • the punch can have different geometries. he can comprise a conforming plate 71 extending over the entire surface of the leaves 21. As a variant, it can understand belts whose geometry is adapted to that of belts 61. It can also be fitted with rollers similar to the rollers 63 of the member 6.
  • pads 163 are used in place of the rollers 63 of the first embodiment, these pads being articulated about an axis X 163 parallel to the conveying direction X-X ', on brackets 164 mounted on posts 165.
  • a plate of curved glass 102 comes to bear on the upper face 163 a of a shoe 163, this face being slightly inclined, by an angle ⁇ less than 20 ° relative to the horizontal, defined by the plane comprising the directions XX 'and YY ′ the face 163a of each pad 163 can also be horizontal.
